A lighting fixture is disclosed with effective disinfection properties against bacteria, fungi, and viruses. The fixture includes a fan to continuously draw air into the light fixture. The air drawn in is irradiated with UV radiation within the fixture, such as is provided from UV LED chips. The relatively small volume of the light fixture allows the flux or energy density of the UV radiation to be made more intense. After the air is sterilized, it can be put back into the room or building in which the fixture is placed. The white light provided by white light LEDs in the fixture provides illumination, and can further provide significant emission peaks at 405 nm and 470 nm which is also useful to pathogen inactivation.

A detoxification device for removing pathogens from air within an environment. The detoxification device may include a filtration media for catching and retaining particles larger than about 0.3 micrometers (μm) with an efficiency of at least 99%. The detoxification device may also include a heating element having a metallic foam. The heating element may be heated upon application of an electrical current to the heating element. The heating element may, upon being heated, heat the filtration media to a target temperature that is effective to kill a pathogen.

The present application provides a wall-mounted air purifier, including casing, a filter installed in the casing, and a fan installed in the casing. The casing is defined by an air inlet and an air outlet, and the air outlet is located at the position corresponding to the outlet of the fan. The filter is arranged between the air inlet and the fan, a photocatalytic module is installed in the casing, and the photocatalytic module is arranged between the air inlet and the fan. The wall-mounted air purifier provided in the present application filters and purifies the air by arranging a filter in the casing; and arranging a photocatalytic module in the casing to sterilize and disinfect the gas entering the air inlet and decompose harmful molecules in the gas for better purifying the air and improving the air purification capacity.

A decontaminating filter table for decontaminating exhaled or ambient air is provided. The table includes an input air grille; a first air trough in fluidic connection with the input air grille; a second air trough in fluidic connection with the first air trough; and a HEPA filter for filtering the decontaminated air. The table also includes an air mover for drawing the exhaled air through the first and second air troughs and through the HEPA filter. In addition, the table includes a scrubber for decontaminating the exhaled air and a visual/audio indicator for monitoring air flow through the first and second troughs.

One variation of a method for detecting pathogens in an environment includes, during a first sampling period: triggering collection of a pathogen sample from ambient air in the environment by an air sampler; and tracking a first organic load of the first pathogen sample via a detection subsystem integrated within the air sampler, the first organic load representative of a first amount of organic matter present in the first pathogen sample. In response to the first organic load exceeding a threshold organic load defined for the environment, the method further includes: interpreting presence of a set of pathogens in the environment via genetic analysis of the first pathogen sample; and, in response to detecting presence of a first pathogen, in the set of pathogens, in the first pathogen sample, transmitting a notification indicating presence of the first pathogen in the environment to a user associated with the environment.

A sanitization apparatus for sanitizing the air in an environment is described as comprising a first filter which is arranged in an internal chamber upstream of a fan assembly, a second filter which is arranged in the internal chamber downstream of the fan assembly, a first ionizer device which is arranged in the internal chamber between the second filter and the outlet, a second ionizer device which is arranged in the internal chamber between the first filter and the second filter, an electronic control unit which controls the second ionizer device to sanitize the second filter.

The present invention provides a wireless rechargeable and portable anti-microbial respirator. The respirator includes a face-piece with an air inlet and an air outlet; a first belt and a second belt, the first belt is connected to ends of the face-piece, and the second belt is configured to wrap around the waist of a user; a flexible outlet tube, where the first end of the flexible outlet tube is connected to the air outlet of the face-piece; a flexible intake tube, where the first end of the flexible intake tube is connected to the air inlet of the face-piece; and a filtration system fixed onto the second belt. The key features of the respirator in the present invention include highly antibacterial and antiviral, long duration, reusable, self-cleaning and self-disinfecting, lightweight and portable, wireless power transfer, and great airflow and comfortable breathing.

An air pumping device providing automatic sterilization and pumping of indrawn air for oxygenation or other purpose comprises a shell with an air inlet hole and an air outlet hole, an electromagnetic assembly, a transmission device, an air pumping module, and a sterilizer element. The transmission device includes a swinging element forth for acting forces in two directions alternatively on the air pumping module, to draw in and pump out sterilized air. The air pumping device has two air pumping modules is also disclosed, the two air pumping modules being arranged symmetrically on either side of the swing element, therefore the swing element creates an indrawing of air and an exhausting of air for every swing.

The present invention relates to a novel isolating consulting table. The novel isolating consulting table includes a table body and an air outlet pipe, wherein an air inlet duct is inlaid on the table top; the air inlet duct and the air outlet pipe are located in the same vertical plane; an electric ion purification and disinfection system is arranged in the air inlet duct; the table body is provided with a pneumatic device; an air inlet and an air outlet of the pneumatic device are communicated with an air outlet of the air inlet duct and an air inlet duct of the air outlet pipe, respectively; the air outlet pipe includes a ventilation pipe, and an air outlet guide hood located at an air outlet of the ventilation pipe; an air outlet side of the air outlet guide hood is arranged toward the air inlet duct.

The present invention provides for a system for disinfecting air circulated in an HVAC system. The system includes a multi-phase system, wherein the multi-phase system comprises at least six segments, with at least one segment representing each of at lease one air intake, at least one air handler, and at least one connecting ductwork. The system has at least one interchangeable filter, wherein each filter in said at least one interchangeable filter is an elongate three-dimensional grid with a series of openings to allow circulated are to flow over the air filter's elongate surfaces. The system also has a plurality of ultraviolet lights, and an airborne disinfecting system with at least one spray nozzle mounted to said at least one connecting duct, wherein a supply hose connects said at least one spray nozzle to at least one reservoir of disinfectant.
